These are the most common doses and are commonly nicknamed T(number), for example T3's

In the UK, Tylenol 1 and 2 come in over-the-counter form as in the US, all of these are prescription.

No doubt, these pills are still really nice to have prescribed for a minor injury, but the reason they are a "tease" is because for those (myself) who try to get high off of the codeine basically have to fucking overdose themselves (myself...) on the tylenol before getting the same buzz.

Don't get me wrong, you can still get a nice buzz off of only 100-200 mg's, but after very few times, tolerance kicks in fast and you have to take toxic levels of tylenol before you can get a nice opiated buzz.

Many people get liver damage all the time and aren't even aware, but after multiple doses, it can get severe and in higher doses, people end up in the hospital or dead.

There is a way to do a cold water extraction to seperate the codeine from acetaminophen, but you lose a lot of codeine doing so, until you can get better at it.

I took 15 Tylenol 3's and 3 vicodin in about 2 hours, which is about 6.5 grams of tylenol and ended up in the hospital throwing up, getting my stomach pumped and eating activated coal.
